ELECTRIC DISPLAY-BURNER FOR OILMLAMPS.

SPECIFICATION forming part of Letters Patent No. 453,041, dated May 26,1891. Application lcd February 16, 1891. Serial No. 381,604. (No model.)

To all whom, t may concern;

Be it known that l, WILLIAM A. DEYsDALE, a citizen of the United States,and a resident of Philadelphia, Pennsylvania, have invented certainImprovements in Electric Display-Burners for Oil-Lamps, of which thefollowing is a specification.

The object of my invention is to provide lamp-dealers and others with anacceptable form of burner whereby an electric lam p can be employed inconnection with the reservoir of any ordinary form of oil-lamp for lthepurpose of displaying the appearance of the lamp and lamp-shade whensaid lamp is lighted. This objectI attain in the manner hereinn afterset forth, reference being had to the accompanying drawings, in whichFigure l represents a side view of my irnproved electric display-burnerfor lamps; and Fig. 2 is avertical section of the same, partly inelevation.

In many stores in which lamps are sold, especially the expensive lampsand shades such as are now sold by jewelers and art dealers, the use ofoil in the lamps while the latter are on exhibition is objectionable,and it becomes desirable to use electric lamps for the purpose ofdisplaying the appearance presented by the lamps and shades when saidlamps are lighted. I-Ieretofore this has been done in a crude way bysuspending an ordinary electric lamp above the reservoir and beneath theshade of the oil-lamp, but thisprecludes the use of a chimney, and is atbest a makeshift plan, and is objectionable.

In carrying out my invention, therefore, I make a burner A, which is, sofar as regards external appearance, the same as the burner of anordinary oil-lamp, and is by preference provided with achimney-holdera., and at the lower end a threaded iiange Z), for screwing into theusual threaded collar on the lamp, although other means of attachmentmay be used, if desired. In place of the usual wicktubes, however, Imount within the burner an ordidary form of electric-lamp socket B,

the conducting-cable for supplying current thereto passing through aprojection CZ (preferably insulated) on one side of the burnercasing, orin such other part of the same as may be most convenient, and theswitch-op erating stem f of the socket is connected to a rod g, whichpasses through an opening in the burner-casing, and has at the outer enda milled head h., similar to that of the wickraisin g shaft of anordinary oil-burner. By this means the electric lamp is securely mountedupon the reservoirand occupies the same position as would the name ofthe oil- `lamp, and a chimney can be used and an ornamental shade can bedisplayed with pre cisely the same eifect as it will have when in actualuse. Moreover, the electric lamp socket is hidden from ordinary view, asis alsothe lamp, when the shade is applied, and the light can be turnedonv and off by lnanipulating a knob at the side of the burner in thesame way as in raising or lowering` the Wick of the oil-lamp.

I therefore claim and Letters Patentl. The withihdescribed electricdisplayburner for oil-lamps, the same comprising the electric lamp, itssocket, and an outer casing inclosing and hiding said socket, the wholebeing constructed for application to the reservoir of an oil-lamp,substantially as specified.

2. In an electric display-burner for oillamps, the combination of theelectric-lamp socket with a casing therefor having an opening for theconductor and means for securing said casing to the reservoir of thelamp, substantially as specified.

3. In an electric display-burner for oillamps, the combination of theelectric-lamp socket with a casing therefor constructed for applicationto the lamp-reservoir and having a holder for a lamp-chimney,substantially as specified.

et. In an electric display-burner for oillamps, the combination of theelectric-lamp socket having a switch, with the outer casing for saidsocket constructed for application to an oil-lamp, a conductor extendingthrough the casing, and a rod connected to the switch-stem and alsoextending through said ou ter casing, said rod having at the outer endaknob or button, substantially as specilied.

In testimony whereof I have signed Iny name to this specification in thepresence of two subscribing witnesses.

WILLIAM A. DRY SDALE.
